PORTO striker Vincent Aboubakar celebrated the Portuguese club's UEFA Champions League DEFEAT against Besiktas last night – by rejoicing with the Turkish club’s players in their dressing room.
The Cameroon star made a shocking show of where his loyalties lie – having shone on loan for Besiktas last season.
But the way he readily joined in the Besiktas party is sure to shock not just his club but football across Europe.
The 25-year-old smiles and gives a thumbs-up sign as Besiktas players laugh in a video posted on Twitter.
Perhaps they themselves could not quite believe what Aboubakar was doing.
But a cheeky message was planted across the video: “My brother @vincentaboubakarofficial09… I miss him.”
He was also a wanted man throughout the summer – but for a different reason.
Swansea and Newcastle were among Premier League teams sniffing around, with talk of a £9million deal.
French side Rennes were also briefly tipped to nab him - before being scared off by his reported £2.5m annual pay.
Everton are also thought to be long-time admirers.
And many were surprised when the £75m sale of Romelu Lukaku to Manchester United was not followed up with a bid for the ex-Lorient frontman.
Aboubakar has hit 22 goals in 47 games for Porto.
And he was a fans' favourite at Besiktas as he netted 12 times in 27 matches.
